The following drag and drop JavaScript works in Firefox, but not in IE:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>t</title>
<style type="text/css">
.mover {
width:60px; height:4em; line-height:4em; margin:10px; padding:5px;
float:left; background:#ffff99; border:1px dotted #333333; text-align:center;
}
</style>
<script type="text/javascript">
function dragWord(dragEvent) {
dragEvent.dataTransfer.setData("text/html", dragEvent.target.textContent + "|" + dragEvent.target.parentNode.id);
}
function dropWord(dropEvent) {
var dropData = dropEvent.dataTransfer.getData("text/html"); var dropItems = dropData.split("|");
var prevElem = document.getElementById(dropItems[1]);
prevElem.getElementsByTagName("div")[0].textContent = dropEvent.target.textContent;
dropEvent.target.textContent = dropItems[0]; dropEvent.preventDefault();
}
</script>
</head>
<body>
<div><em>Move the words around to make a sentence.</em></div>
<form>
<div id="box1" ondragover="event.preventDefault()" ondrop="dropWord(event)">
<a href="#" class="mover" draggable="true" ondragstart="dragWord(event)" >page</a>
</div>
</form>
</html>
Does anyone have any clues as to why this does not work in IE? The problem is in the drag and drop function. I tried to replace the div with a href=# but that does not work.

What I want to achieve here is that on scrolling down the document I wanted the "h1 tag to fade in and appear as soon as I reach id="second". How to do that with JS. I have tried a couple of things, but nothing is working out the way I want. I also browsed regarding animation on scrolling and got results but I m not getting what's happening really. Can someone plz help me out in this? I m completely new to JS and trying out various kinds of stuff.
Thank you.
If you want to use the fade-in for multiple elements. Give a class to these elements and use the loop which is already commented.
$(document).ready(function() {
$(window).scroll( function(){
// $('.fadein').each( function(i){
var bottom_of_element = $('#welcome').offset().top + $('#welcome').outerHeight();
var bottom_of_window = $(window).scrollTop() + $(window).height();
if( bottom_of_window > bottom_of_element ){
$('#welcome').animate({'opacity':'1'},1000);
}
// });
});
});
div {
height: 600px
}
#first {
background: red;
}
#second {
background: green;
}
#welcome {
opacity: 0;
}

I cannot for the life of me figure out why the text under Sub1 and Sub2, do not show the text under them, when clicking them. Only the first link "Main Category" functions. It is making me enter more description, though the issue is already explained the best I know how.

You have a typo in your JS $('.commentsTitle').click(...
In the html you assigned the class commentsTitle, in the JS, you referred to commentTitle.
$(document).ready(function(){
$('.showArticle').hide();
$('.articleTitle').show();
$('.showComments').hide();
$('.commentsTitle').show();
$('.articleTitle').click(function(e){
$(this).next('.showArticle').slideToggle();
e.preventDefault();
});
$('.commentsTitle').click(function(e){
$(this).next('.showComments').slideToggle();
e.preventDefault();
});
});

I try to drag the image and drop it on the target div. However instead of dropping the image itself only the image path is displayed.
Html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="DragAndDrop_2.css">
<script src="DragAndDrop_2.js" type="text/javascript"></script>
</head>
<body>
<img id="my-image" draggable="true" src="images/thumbUp.jpg" height="200">
<div id="target-box"> </div>
</body>
</html>
Stylesheet:
*{
margin:0px;
padding:0px;
}
#target-box {
width:600px;
height:600px;
border:1px solid black;
}
Javascript:
function initialFunction() {
picture = document.getElementById('my-image');
targetBox = document.getElementById('target-box');
picture.addEventListener('drag', drag, false);
targetBox.addEventListener('dragover', function(ev) { ev.preventDefault(); }, false);
targetBox.addEventListener('drop', drop, false);
}
function drag(ev) {
ev.dataTransfer.setData("Text", ev.target.outerHTML);
}
function drop(ev) {
var code = ev.dataTransfer.getData("Text");
targetBox.innerHTML = code;
}
window.addEventListener('load', initialFunction, false);
I heard about some issues with Drag and Drop operation in HTML5. I wonder if in this case it's a bug in API or perhaps I'm missing something.
I'm learning JavaScript and created a countdown timer HTML page in which javascript code seems to be returning a wrong clientHeight of the body. I want to show my countdown HTML <div> in middle (vertically) of the body even when browser is re-sized. Please tell me where I am wrong.

Please, give me some tips how to keep <div> vertically centred even if browsers are re-sized.
You don't need JS for that.
#in_the_middle {
position:fixed;
left:50%;
top:100%;
width:200px;
margin-left:-100px; /* MUST be equal to width * -0.5 */
height:50px;
margin-top:-25px; /* SHOULD equal height * -0.5, but can vary for different fx */
line-height:50px; /* Remove if there may be more than one line inside */
}
I have a grid with an template column and in that column I have text and icon,
on icon mousehover (on mode) and mousehoverout (off mode) I am changing the icon.
Now when the user click on icon it opens a popup and the icon must be in "On" mode but if the user without closing clicks another row's icon then previous must be in off and current should be in on mode.
So for that I have written this:
<DataItemTemplate>
<div class="floatLeft titleBlock">
<a href="<%# Eval("Link") %>" class="ellipsesTooltip"><span>
<%# Container.Text%></span><%# Container.Text%></a></div>
<div class="floatRight">
<a onclick="GridValueCatcherMoreLike(this, '<%# Eval("ResearchNoteId").ToString()%>');">
<img alt="+/- 30 days matching Author, Industry, Theme" src="../Image/Research/MoreByOff.gif" onClick="check(this,'../Image/Research/MoreByOn.gif', '../Image/Research/MoreByOn.gif');"
onmouseover="ToggleAuthorMoreLikeImage(this, 'MoreLikePopUp', '../Image/Research/MoreByOn.gif', '../Image/Research/MoreByOff.gif');"
onmouseout="ToggleAuthorMoreLikeImage(this, 'MoreLikePopUp', '../Image/Research/MoreByOff.gif', '../Image/Research/MoreByOff.gif');" />
</a>
</div>
function check(sender, onImg, offImg) {
debugger;
for(var i=0;i<activeImgList.length;i++)
{
if(sender!=activeImgList[i])
activeImgList[i].scr = offImage;
else
activeImgList[i].scr = onImg;
}
return true;
}
function ToggleAuthorMoreLikeImage(sender, popupname, imageurl, offImageurl)
{
var win = ResearchPopup.GetWindowByName(popupname);
if (!ResearchPopup.IsWindowVisible(win))
{
sender.src=imageurl;
activeImgList[arrayIndex]=sender;
arrayIndex = arrayIndex + 1;
}
else
{
activeImgList[arrayIndex] = sender;
arrayIndex = arrayIndex + 1;
return;
}
}
Why not take a step back and use something like jQuery.toggleClass() or jQuery.hover() on the client side?
.hover()
<!DOCTYPE html>
<html>
<head>
<style>
ul { margin-left:20px; color:blue; }
li { cursor:default; }
span { color:red; }
</style>
<script src="http://code.jquery.com/jquery-1.5.js"></script>
</head>
<body>
<ul>
<li>Milk</li>
<li>Bread</li>
<li class='fade'>Chips</li>
<li class='fade'>Socks</li>
</ul>
<script>
$("li").hover(
function () {
$(this).append($("<span> ***</span>"));
},
function () {
$(this).find("span:last").remove();
}
);
//li with fade class
$("li.fade").hover(function(){$(this).fadeOut(100);$(this).fadeIn(500);});
</script>
</body>
</html>
.toggleClass()
<!DOCTYPE html>
<html>

<style>
p { margin: 4px; font-size:16px; font-weight:bolder;

<p class="blue">Click to toggle</p>

$("p").click(function () {
$(this).toggleClass("highlight");
